To calculate: The equation of a circle whose end points of diameter are

Answer to Problem 98E
The equation of the circle is
Explanation of Solution
Given information:
The end points of diameter of the circle are
Formula used:
The standard form of the equation of the circle is
Distance
Midpoint of the segment that joins two points
Calculation:
Consider the provided conditions that end points of diameter of the circle are
Now, the center of the circle is the midpoint of the diameter.
Recall that the midpoint of the segment that joins two points
Evaluate the midpoint of the segment that joins
Therefore, coordinates of center are
Now, the radius of the circle is distance between the center of the circle and any one end point of diameter.
Recall that the distance
Evaluate the distance between
Therefore, radius of circle is
Recall that the standard form of the equation of the circle is
Compare,
Here,
Substitute the values in standard equation of circle,
Thus, the equation of circle is

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
